Product
The products covered by this manual are
the BPF fused substation by-pass switches
for medium voltage electrical distribution
switching.
These products are designed for distribution
switching only at their rated capacities. They
cannot be field modified for capacities other
than what was shipped with the units. If a
different capacity is desired, contact your
supervisor or factory representative to se-
cure the appropriate unit.
Overview
Function
These products are non-loadbreak discon-
nect switch and fuse combinations designed
to provide a means for by-passing, discon-
necting and isolating reclosers on the elec-
trical distribution system.
General
The BPF By-Pass Switch is a single-phase
fused hook stick operated switch. It is nor-
mally used with a companion switch such
as a Chance M3S, station class hook stick
switch. The BPF By-Pass switch is used for
manually disconnecting a recloser without
interrupting normal electrical service while
continuing to provide over-current protec-
tion. Standard variations are:
A. Left or right fuse mounting.
B. Te rminal connectors.
The BPF disconnect switch has no inherent
current making or breaking rating. The fuse
is capable of interrupting over-currents
within its assigned rating. Both switch and
fuse include load break hooks for use with a
load break tool. The BPF has no dead-end-
ing provisions.
Specifications
Select the proper BPF switch for each in-
stallation with consideration to system and
short circuit recovery voltage, continuous
current, available short circuit over-current,
short time current withstand, lightning im-
pulse withstand and variations. If there is
concern about the use of this switch as
rated, consult your supervisor before instal-
lation.
Nominal voltage ratings of 14.4kV or
25kV (model dependent)
Lightning impulse peak withstand ratings
of 110kV or 150kV (model dependent)
Switch continuous current rating of 600
amperes
Switch short time current withstand
rating:
25kA symmetrical, 1 second
65kA peak
Fuse continuous current ratings of 100 or
200 amperes (model dependent)
Fuse interrupt ratings of:
14.4kV nominal voltage rating
7.1kA symmetrical, 10kA asymmetrical
for 100 ampere fuse holder
8kA symmetrical, 12kA asymmetrical
for 200 ampere fuse holder
25kV nominal voltage rating
5.3kA symmetrical, 8kA asymmetrical
for 100 ampere fuse holder
6.6kA symmetrical, 10kA asymmetrical
for 200 ampere fuse holder
Rating of the fuse holder is given on the
switch name plate. Consult factory repre-
sentative prior to using any other fuse
holder.
Switch Variations
A. Left or Right Fuse Mounting
Left or right fuse mounting may be speci-
fied. A left mounted fuse is to the left of the
operator when viewed from the front of the
switch. A right mounted fuse is to the right
of the operator when viewed from the front
of the switch. This selection allows the BPF
to be tailored to fit the requirements of the
application. Illustrations in this manual show
only a left fuse mounting. Right fuse mount-
ing will be opposite as shown but does not
change the installation or operation
procedures. (continued next page)

CAUTION
Installation
Install an appropriately rated fuse link in
the fuse holder.
•To install the fuse link in the fuse holder,
remove the cap from the upper ferrule of
the fuse holder assembly.
•To connect the fuse link and arc shortening rod, remove the screw-type button-head and
washer (if equipped) from the fuse link.
Screw the arc-shortening rod (attached to cap) onto the fuse link and tighten firmly (See
Figure 2).
Slide the fuse link cable into the top of the fuse holder and pull out at the lower end.
Replace the cap or arc shortening rod assembly on the upper fuse holder ferrule and
tighten with a wrench.
Holding the fuse holder at the lower end, rotate the link ejector about its pivot until it stops,
making certain that the tab on the link ejector engages the latch on the lower fuse holder
ferrule (See Figure 3).
Hold the ejector in this position and feed the cable over the link ejector channel and in a
clockwise direction around the un-threaded portion at the base of the stud (See Figure 4).
•Maintain tension on the fuse link cable and tighten the fuse link attachment nut with a
wrench.
Cut off excess fuse link cable.
High Voltage Electrical Arc Hazard
May cause moderate injury or property damage.
Do not remove or damage the small tube on the fuse link. It is an integral part of the fuse link and removal or dam-
age may result in the fuse’s failure to interrupt an over-current.
Install Fuse Link
High Voltage Electrical Arc Hazard
May cause moderate injury or property damage.
Do not use 100 ampere or smaller fuse links in 200 ampere fuse holders by employing washers or other means.
This action may result in the fuse’s failure to interrupt an over-current.
High Voltage Electrical Arc Hazard
May cause moderate injury or property damage.
Do not replace an arc-shortening rod with a standard cap. The rod is
required to achieve the designed interrupting rating and use of the
fuse holder without the rod will reduce the fuse’s interrupting capabil-
ity and may cause the fuse to fail to interrupt an over-current.
NOTE: Fuse holders using an arc-shorten-
ing rod require the use of removable button-
head fuse links.

Use sufficient conductor length to allow
for ease of termination and switch
operation
Connect High Voltage
Conductors
•Wire brush mating surfaces of the
terminal pads and terminal connectors
•Wire brush connector surfaces where
conductors will be secured
•Wire brush conductor surfaces
Apply a contact sealing paste to the
cleaned surfaces (Chance Co. Z.L.N. or
equivalent)
Assemble connectors, conductors and

Ensure bolt heads of the terminal
connectors are on the insulator side of the
terminal pad as shown.
•Torque all supplied hardware to 60 ft-lb.
•Torque user supplied hardware according
to your company standards.
High Voltage Electrical Arc Hazard
May cause property damage.
Install terminal connectors with bolt heads toward the insulator.
Failure to do so may compromise the electrical insulation resulting in
an electrical arc.

•To close the switch, place a hook stick in
the pull ring on the blade and rotate the
blade to an intermediate position as
shown in Figure 7.
•Turn head and look away from the switch.
General
Operation of the BPF By-Pass switch is
shown in Figures 4 and 5. In normal
operation, the fuse holder is not in place
and the companion switch and by-pass
switch disconnect blades are closed (Figure
5), allowing the recloser to be in the circuit.
When isolation of the recloser is required,
install the fuse holder fitted with an
appropriately-rated fuse link and close the
fuse holder to provide a parallel current
path. Open the disconnect blades (Figure
6) to isolate the recloser from the circuit.
•Position yourself below and slightly to the

Maintenance
General
Extend the life of the BPF By-Pass switch with
a periodic inspection and maintenance pro-
gram. Although the switch is designed for long-
term exposure in all weather conditions, cer-
tain environments may reduce its life without
periodic maintenance. Following these mini-

DANGER
Hazardous Voltage
Contact with energized lines will result in death, personal injury or property damage.
All maintenance work should be performed on de-energized switches. If work must be performed on live lines, follow your
company’s standard safe operating procedures.
Hazardous Voltage
Contact with the switch base or hardware could result in electrical shock. Can cause death or severe personal injury.
Always ground the switch base and mounting hardware prior to maintenance.
!
WARNING
mum inspection and maintenance procedures
will help ensure long service life.
Note: It is recommended that all switches
go through a maintenance check at least
once a year; more frequently if located in a
contaminated area.
Fused By-Pass Switch
Operate the switch periodically to clean con-
tact surfaces to keep parts moving freely.
Check for burned or pitted contacts and
replace if necessary. Lubricate if neces-
sary with Optimol

Inspect all blade rivets for tightness and
replace blade assembly if loose.
Inspect the mounting hardware and
tighten according to specifications located
in the Installation Section of the manual.
Replace any damaged or tracked insula-
tors. Clean or replace if heavily contami-
nated. Consult your factory representative
for authorized replacement insulators.
Replace fuse holder if it shows signs of
